CORRUGATED AUTO MARINE VEHICLE.

Application flied January 22, 1927. seriai No. 162,757.

This invention relates to an auto marine vehicle or land and water craft constructed to afford great strength by producing the hull and pontoons of corrugated metal.

It is an object of this invention to provide a land and water craft whereinthe hull and the pontoons therefor are both constructed of corrugated sheet metal to permit the corrugated pontoons to lockingly intert in the corrugated pockets formed in the sides of the corrugated vehicle hull.

It is an important object of this invention to provide an auto marine vehicle wherein Athe hull or body is constructed of corrugated metal to afford a hull of greatV strength and one wherein the pontoon pockets formed in the side of the hull, also being corrugated, permit the corrugated pontoons movably mounted on the sides of the hull to lockingly interfit the same, in either the raised or lowered positions of the pontoons.

Other and further import-ant objects of this invention will be apparent from the disclosures in the specification and the accompanying drawings.

This invention, in a preferred form, is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure l is a side elevation of a corrugated auto marine vehicle embodyingthe principles of this invention.

Figure 2 is an enlarged vertical transverse section taken on line lle-H of Figure 1.

Figure 3 is an enlarged fragmentary detail section of the hinge and pontoon taken on line III-III of Figure 2.

Figure 4 is an enlarged fragmentary dei tail section of the pontoon hinge and the hulll taken on line IV-IV of Figure 2.

Figure 5 is an enlarged fragmentary detail section taken longitudinally through a Y v portion of the hull on line V-V of Figure 2.

Figure 6 is an enlarged section of the deck of the hull taken on line Vil-VI of Figure 2.

As shown on the drawings:

The improved auto marinevehicle of this invention comprises a hull constructed of corrugated sides l, a corrugated deck 2 and a corrugated bottom 3. The corrugations are drawn to a point or lesser dimension in forming the bow, sternand other' diminished areas, thus affording great strength and eliminating largely the twist tendency in the metal. While the deck or roof of the auto marine hull is shown as being transversely corrugated7 said deck may be constructed with the corrugations disposed diagonally to produce lateral strength to resist twist tendency without the use of reinforcing ribs. The corrugated bottom 3 affords runners without the need of protecting strips, with the runners serving as a means to reduce friction and wear when effecting a landing. rilhe sides of the hull are provided with upper corrugated pontoon pockets 4- and lower corrugated pontoon pockets 5. The interior of the hull is provided with T cross sectioned ribs or braces 6 to afford a strong framework forthe corrugated hull. Mount`- y ed on top of the deck 2 is a vehicle top 7 of any desired construction. Rigidly secured on each side of the hull at the line ofintersection between the upper and lower pontoon' pockets 4t and 5 are a plurality of spaced links or hollow supports 8 which support a hollow hinge tube or shaft 9 on which spaced link members or sleeves l() are pivotally Aengaged, in alternate relation with the hinge links 8. Y A.

The hinge sleeves l0 are securedlongitudinally in a line on a corrugated pontoon ll' one of which is disposed on each side of the vehicle hull. Each of the corrugated pontoons ll is provided with a cylindrical intermediate section and tapering closed ends, as clearly illustrated in Figure l. The interior of each of the pontoons 1l is reinforced by metal ribs or hoops 12. As illustrated in Figures l and 2 the auto marine vehicle is provided with rear driving wheels ,13 and steering wheels 14. Y

If desired the corrugated plates forming the hull may be arranged to inter-lap along the pontoon hinge lines to form a construction of double strength along the hinge lines. Parts of the overlapping margins of the plates may be used to form parts of the hinges.

The adjustable pontoons 1l may be moved from their lower position in which they are lockingly engaged with the corrugations of the lower pockets 5, into their upper positions by any suitable mechanisms, permitting the pontoons when raised to pivotabout the hinge shaft 9 until the lcorrugations of the pontoons lockingly seat in the corrugations of the upper hull pockets 4;. The pontoons when adjusted may be secured in their respective hull pockets by any suitable ico means with said pontoons having a tight fit with the hull pockets to afford an improved water craft, of particularly strong and durable construction, and able to withstand heavy seas when the vehicle is used in the water. If desired, all the exposed walls of the vehicle may be constructed of corrugated metal properly reinforced by brace ribs of any desired construction.

The improved hull by being constructed of corrugated sheet metal affords a surplus of metal permitting repairs to be easily made in case the hull becomes ammed or bent. The inner grooves of the hull, formed by the corrugationsin the metal, may be filled with rubber compound or any suitable deadening substance to retard sound and also make the hull waterproof.

I am aware that many changes may be made, and numerous details of the construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon', otherwise than necessitated by the prior art.

I claim as my invention:

l. An auto marine vehicle comprising a corrugated hull and corrugated pontoons mounted thereon and tapered at the ends,

said pontoons having the corrugat'ions eX- tending the full length thereof with the end portions of the corrugations tapered.

V2. An auto marine vehicle comprising a longitudinally corrugated hull, a transversely corrugated top, wheels for supporting the hull, and corrugated pontoons mounted on the side of the corrugated hull, said pontoons having tapered ends provided with tapered corrugations.

3. An auto marine vehicle comprising a corrugated hull, having corrugated pockets formed in the sides thereof, corrugated pontoons disposed on opposite sides of the hull and hinge means for pivotally supporting said corrugated pontoons in position to seat in said corrugated pockets.

4. In an auto marine vehicle the combination with a corrugated hull having corrugated pockets therein, of tapered and corrugated pontoons pivotally mounted on the hull to lockingly interit said pockets.

5. In an auto marine vehicle the comb-ination with a hull having pontoon pockets formed therein, of corrugated pontoons pivotally mounted on said hull adapted to seat in said pockets.

6. In an auto marine vehicle of the class described, the combination with a corrugated hull having corrugated pockets formed therein, of corrugated pontoons pivotally mounted on said hull intermediate the pockets to permit the corrugated pontoons to be lockingly seated in interitting relation in said pockets.

7. An auto marine vehicle comprising a corrugated hull, reinforcing ribs mounted therein,said hull having corrugated upper and lower pontoon pockets formed in the sides thereof, hinge members l secured on each side of the hull at the line of intersection of the upper and lower pockets, corrugated pontoons disposed on opposite sides of the hull, and hinge means for pivotally connecting said corrugated pontoonsvwith ysaid hinge members to permit the corrugated Vpontoons to Alockingly interfit in the corrugations of either the upper or lower pontoon pockets of said hull.

8. A water craft comprising a corrugated hull, and corrugated means adjustably mounted thereon to vary the draft thereof and lockingly interlit lwith the eorrugations of said hull.

9. A water `craft 4comprising a longitudinally corrugated hull, a transversely corrugated deck therefor, said hull having corrugated upper and lower pockets formed in the sides thereof, hinge means connected with the exterior of the hull between the lpockets on each side thereof, longitudinally corrugated hulls connected to said hinge means adapted to lockingly interfit with said corrugated pockets, said pontoons having tapered closed ends provided with tapered corrugations which are continuations of thelongitudinal corrugations of said pontoons.

10. A water craft comprising a hull having corrugated pockets formed in the sides thereof, a plurality of spaced links rigidly secured on the sides of said hull, a tubular shaft supported by said links on each side of the hull, a tapered pontoon positioned on each side of said hull and having corrugations formed longitudinally thereon and eX- tending the full length of the pontoon with the ends of said corrugations tapered to meet at the ends of the pontoon, and spaced sleeves integrally formed on each of said pontoons and pivotally engaged on one of said tubular shafts to pivotally support the pontoon in position and lockinglyl interfitv in the corr-ugations of one of said pockets.

l1.
